The topic How to use FTPS (introduction) describes the FTPS features of SecureFTPConnection. This topic demonstrates the use of FTPS without server validation. Server validation should always be used in a production environment, but disabling it is a good way of getting started.
IMPORTANT: An FTPS compatible FTP server is required for this example. You can download a free trial of CompleteFTP, a Windows FTPS server, from this link .
Using FTPS without server validation is simply a matter of setting the Protocol and ServerValidation properties as follows:
fftpConnection.Protocol = FileTransferProtocol.FTPSExplicit;
ftpConnection.ServerValidation = SecureFTPServerValidationType.None;The first line tells SecureFTPConnection that it is to use explicit FTPS and the second line that it should not try to validate the server's certificate.
After this a secure connection is established by simply calling Connect():
ftpConnection.Connect();
